Lol! You may not live through that little test then
The dust mite thing actually makes a LOT of sense, especially if they are not new. AND, most people only wash the covers and not the actual pillows/duvets themselves because of the down (although I have mine dry cleaned.....I think that's basically a waterless cleaning but they still get heated up--is that right?) I wonder if you could have them dry cleaned and problem solved?? Wouldn't that be great!
